2007 6MT ~95k....had just finished installing new LED lights on front end, and started it up and noticed a faint but definitely audible whining sound coming from the front of the engine bay, also audible in the cab while idling and driving at low speeds. Not sure if this has anything to do with alternator/new light install or if that part is coincidence, as lights do not need to be on to hear the whine. Rig does see good use, i.e. Dust, mud, rocks, snow water etc. wondering if it could be idler pullies, power steering pump, fan belt, alternator, or something else. If anyone has had similar issues I would love to hear some input. Will post video update with sound
